Application filed May 8, 1906. Serial No. 259,160.

Be it known that we, EDWARD S. LEA, a citizen of the United States, and demos Dncan, a citizen of the Republic of Switzerland, residing at ircnton, in the county of Mercer and State of New Jersey, have invented certain new and useful lmrovements in Automatic Packing, oi whic specification. i

The invention has reference to means for packing rotatably mounted shafts in their earings, and is more especially directed to means for automatically compensating for the wear which occurs at the bearings, and is the pee pressure equal to-that oi the pressure on either side of said packing devices, so as to 'ters of reference apply to similar also to povide means whereby when desired ng device may he flooded withja prevent leaking from the packin devices.

The application of this invention to various purposes in the various arts is contemplated, and one of the arts in which the invention maybe considered especially applicable is that comprehendin various t pes 0t centrifugal pumps for pac ring the s alt at points where it passes through the pumpcasing, as well as where it passes through the partitions forming the cells therein. Ry this citation of an instance of the application of this invention, however, it is not to be construed that the scope of this invention is limited to such articular application.

An embo iment of the invention is illustrated by the accompanying sheets of drawin s, whereon igure 1 illustrates a view in elevation and in section of a form into which the invention may be embodied. Fig. 2 illustrates asimilar view showin a different form of construction. Fig. 3 il ustrateslstill another form. Fig. 4 illustrates an elevational view in section of a packing-ring. Fig. 5 illustrates a orspective view of the same.

In the several illustrations similar characparts.

The bore ll of a ortion 12 of a pump-casing where the packing device is placed is larger than the shaft 113, which may beproed with a collar M, carried in the present instance by a sleeve which collar within the range of mechanical if desired, be formed on the shaft.

Mova

the following is a i occupies a chamber 24, or a source of pros packing element all) against borneby-the shai't but,

sure through a conduit 25, screw-threaded, as at 26, into an opening 27, formed in the journal 18 of the rotating member.

The packing devices comprehending the packin elements, rings, and spring maybe secure upon the sleeve 16 bya nut 28, which may be screw-threaded onto a screw-threaded portion 29 of the sleeve and may be 0 erated by an implement, (not shown,) w ich may take into sockets '30, and this nut may he secured in place by a yam nut 31, which may also be screw-threaded onto the screwthreaded ortion 29 and -may also be provided with sockets 32 to receive the implement.

In the form illustrated in Fig. 2 the sleeve 16 may be provided with a screw-threaded portion 33, to which may be secured a nut 34, which may be secure in place by a jamnut 35, and these two nuts will take the place of the collar l4. (illustrated in Fig. 1.)

In the form illustratedin Fig. 3 the ring 37, which corresponds to the ring 19, (illustrated in Eig.l,) may be screw-threaded, as at 38, onto the sleeve 16. The spring 23 will be limited in its movement in this direction by the location of this sleeve, and in this form the floating ring 39 is adapted to press one a flange.

As appertaining to the structures thus far described, the packing elements 21, 22, and

40 may be-of annular construction and may comprise two angularly-related portions 43 5 and id, the latter being provided with an opening 45 to accommodate the sleeve 16 and the former extending laterally and referably substantially at right angles to t e latter. K lit Will be understood, of course, that the packin elements may be formed of anysuitable su stance or material ,leather being considered practical. .To accommodate the laterall i-extending-jections 43 of the packing s ements, therings 19 and 20 may be pro vi ed with recesses 46."

ing element 4. A construction for automatically sineea prehends instrumentalities take place in taking up the wear which may l such devices. it will also be observed that we provide a packing device which can be floodside thereof, consisting of a sleeve surrounding the shaft, and fixed to the shaft a collar rotating with the shaft, a flexible packing element having right-angularly-disposed walls, one of whichmay be pressed against the collar and the other against a surface at right angles to the collar and. parallel to the shaft, a member fitting in the angular recess of the packing elements and means to press the packing and the member against or toward the collar.

5. A construction for packing rotating shafts against the leakage of fluid on either side thereof, consisting of a sleeve surrounding ed with a pressure whereby to' equalize the pressure on either side of thepacking and prevent leakage;

It will now be seen that the packing elepreferablymay constitute angularly-formed flexible rings, cups, washers, or against, the collar on the shaft and the other portion on a part remote from'the shaft, but

arallel therewith. Within the purview of this invention we ing with the shaft, flexible packing elements each having rightangularlydisposed walls one of each of which may be pressed against the collars in opposite directions and the other against surfaces at right angles to said blage of parts adapted to produce the results sought to be obtained, and therefore it must be understood that the constructions illusthe detail description thereto appertaining, shall not be construed as. confining this invention to the particular form of mechanism herein illustrated'and described.

Having thus claim- 1. A construction, for acking revoluble shafts against leakage of uid on either side thereof, consisting of the shaft, a sleeve surrounding said shaft, and fixed to the shaft a collar thereon, a flexible packing element having angularly-disposed walls, one of which is adapted to press against said collar, and the other against a surface at right anparallel to the shaft.

2. A construction for packing revolving shafts against the leakage of fluid on either side thereof, consisting of a sleeve surrounding the shaft, and fixed to the shaft a collar rotating with the shaft, a flexible packing element having right-angularly-disposed walls, one of which may be pressed against said collar, and the other against a surface at right angles to said collar and parallel to the shaft, and means to press said walls of said element in both directions and against both surfaces.

3. A construction for packing revolving shafts against the leakage of fluid on either sleeve surrounding the shaft, and fixed to the shaft a collar rotating with the shaft, a flexible packing element having right-angularly-disposed walls, one of which may be pressed against said collar, and the other against a surface at right angles to said collar and parallel to the shaft, I
